STATION AND STREET INDICATOR.

SPECIFICATION forming part of Letters Patent No. 406,170, dated July 2,1889.

Application tiled December 17, 1888. Serial No. 298,767. (No model.)

To all whom it may con/cern.-

Be it known that I, CHARLES H. JENNE, of Indianapolis, Marion county,and State of Indiana, have invented certain new and useful Improvementsin Station and Street Indicators; and I do hereby declare the followingto be a full, clear, and exact description of my invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to the class of indicators known as station andstreet indicators,7 of which the devices illustrated and described iiimy former patents-viz., street and station indicators, patented March18, 1884, No. 295,405, and February 3, 1885, No. 311,586- are examples.

The object of this invention is to improve the devices heretoforementioned and provide my new device with mechanism simple inconstruction to operate successfully an apron for successivelyindicating at the proper times the stations or crossings to which thestreetcar, steam-car, or steamboat -is approaching,

and in the same time displaying to the passengers thereon the names ofsuch streets,

corner numbers of houses, and advertisements of business-houses as maybe placed upon the apron located on street-corners or stations along theroute of travel of cars or steamers; and it consists in the constructionhereinafter described and illustrated in the drawings, and moreparticularly related to in the claims.

In the drawings iiled herewith, Figure 1 is a front view of myindicator. Fig. 2 is an end view of the same. Fig. 3 is a view of Fig.l, the lid 2 being removed and exhibiting the interior working parts ofmy indicator, partly in elevation and partly in sectional view. Fig. 4is a sectional side view of Fig. 3. Fig. 5 denotes a portion of mydevice in top view. Fig. 6 is an enlarged detail view of myinvention,hereinafter set forth. Fig. 7, Sheet 2, is a portion of au enlargedsectional side detail view of parts of my invention-namely, roller 4.Fig. Sirepresents a top view of Fig. 7, partly sectional and partly intop view.

In Fig. 1, 1 represents the apron having printed thereon the name of astreet and the corresponding number of the street where thebusiness-house is located and the name of openings of rollers 4 and 5,and extending laterally through the partition-wall 10.

8 and 9 are sprocket-wheels loosely mounted over the hollow spindles Gand 7, and said sprocket-wheels are provided on the inner side andfacing the rollers 4 and 5 with teeth such as are used in crown-wheels.The peripheries of said wheels are provided with sprockets to receivethe endless sprocketchain 20, to impart motion to rollers 4 and 5.

11 and 12 are catclrpawls inserted loosely into the ends of rollers 4and 5, the long vertical arms of which are hinged at 13 and 14. Theother horizontal arms are extendedout of the rollers, and are made toengage with the crown-teeth of the sprocket-wheels 8 and 9 by means ofthe connecting-rods 16 and 17, which rods are centrally located in thehollow spindles G and 7, and are held in position therein by beinghinged on one end to the catchpawls l1 and 12, and the other end by anopening provided in case 3, which serves as a supportl for said rods. Bymoving the inclined plates to and fro and having loosely insertedshoulder and nut, into t-he slotted portion of said plates 19, a lateralmotion to the rods is derived, forcing catch-pawls 13 and 14 alternatelyinto and out of engagement with crownteeth of the sprocket-wheels 8 and9.

21 in Figs. 3 and 4 is a block made of iron, wood, or other material,and is inserted into a compartment provided for this purpose. On theupper end of this block is attached the end of a rope 22, which passesvthrough the case 3 over pulleys to the party operating the saine. Acrank-shaft 23 passes through said block 21, and said shaft is providedon the inner end with a yoke-lever 24. (See enlarged view, Fig. 6.)

28 is a V-shaped spring inserted into an aperture in block 2l, pressingagainst a stop` IOO pin 27, proj eetingl upward on crank-shaft 23. Byturning the handle of the shaft the pin 27 will rotate with the same andkeep one arm of the `yoke in engagement with the corre-V sponding sideof the endless chain 20. As can readily be seen, this block 21, pulledupward and being engaged with sprocket-chain 20 by one arm of the yoke2l, serves to transmit a rotary motion to the rollers et and 5.

The mode of operatingmy device is as follows: Having fastened myindicator on the proper place in a street-car, steam-car, or steamer,and provided the same with the apron and operating mechanism asillustrated and described, (and I intend to indicate the approachingstreet-corner, corner-number, or businesshouse so indicated on theaprem) I move the handle of crank-shaft 23 partly to theleft, (see Fig.2 in dotted lines,) engaging the yoke with the sprocket-chain 20, andalso the inclined plates in the v same direction, thus throwing intoengagement the upper catch-pawl 12 with the crown-teeth of thesprocket-wheel 8. Now, by pulling the block 2l upward by the rope 92, Irotate the roller i and bring into view the desired naine or number ofthe street-corner and advertisement printed on the apron. By releasingthe rope 22 the block 21 on account of its weight will drop downward,striking an annunciator by a suit. ble device, and so callin g theattention of passengers to such station, the. At or near the nextstation or corner of a street the same manipulation is repeated untilthe car, strcet-car,or steamer arrives at the end of the route. Onreturning I reverse the action of inclined plates and yoke,

and thus liberate roller i and engage roller 5. I

Having described my invention in such a manner that those familiar withindicators can construct and operate the same, what I elaini as new,Vand desire to secure by Letters Patent, isil. In an indicator of thecharacter described, the main casin g, a vertical gravitatin g block atthe side thereof, a crank-shaft passing through said block, and ayoke-lever on the inner end thereof, in combination with rollers withinsaid casing, an apron on said rollers, for the purpose set forth, andmeans for imparting rotary motion to said rollers.

2. In an indicator for street-cars, 85e., the main casing, rollerstherein, sprocket-wheels mounted on the ends of said rollers, and anendless sprocket-chain engaging said sprocketwheels, in combination witha block located at the side 0f the main casing and formed with anopening, a V-shaped spring in said opening, a crank-shaft having anupwardlyprojecting pin adapted to engage said spring, a yoke-leversecured on the inner extremity of said crank-shaft, and a rope or chainhaving its end secured to said. block, all substantially as and for thepurposes set forth.

3. In an indicator for street-cars, dac., the main casing, rollers journaled therein, hollow spindles at the extremities of said rollers,and an apron connecting said rollers and adapted to serve the purposespecified, in combination with sprocketwhecls mounted on said spindlesand having their inner faces formed with crown-teeth, an endlesssprocket-chain engaging said sprocket-wheels, and pawls, one member ofcach of which is pivoted within one of said hollow spindles, and theother member extends out therefrom and is adapted to engage thecrown-teeth of one of said sprocket-wheels, as set forth.

4. In an indicator for street-cars, dac., the main casing, rollersmounted therein and located one above the other, apron on said rollers,for the purpose specified, sprocket-wheels mounted on the journals ofsaid rollers and having crown-teeth on their inner faces, and an endlessysprocket-chain, in combination with hinged pawls located partiallywithin the ends of said rollers and adapted to en gage the crown-teethof said sp1'ocket-wl1eels, sliding plates, and rods connecting saidplates and pawls, all substantially as and for the purposes specified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CHARLES ll. JENNE.
